Its realization |K| is a topological group (at least when K is countable). The realization of the W-construction yields a universal |K|-bundle over |overline W K|. THere should be a canonical map from the latter to the bar construction B|K| on |K|. Has this been worked out somewhere in the literature? Many thanks in advance.
